QuoteWin 7 DoS by RA PacketsExecutive SummaryThis is extremely dangerous! A single device can instantly stop all the Windows machines on a Local Area Network. In my tests, my Windows 7 virtual machine freezes totally and the only way to revive it is shutting the power off--an abnormal shutdown.Imagine the effect of a single attacker on a small business, Internet coffeehouse, or any other LAN. This works on all Windows machines with IPv6 enabled, which includes Vista, Win 7, Server 2008, and more. Suppose someone writes this into a malicious Web attack, so everyone who views a malicious Web page instantly kills all the machines on their LAN!As far as I know, this attack will not traverse routers, so it "only" affects your local broadcast domain. But isn't that enough to deserve a security alert and a patch? Apparently not.
